After new firmware updated my ST16 out of control, the gambal tilt control slider and both height slider became motor on off switch(the ref button switch totally on response) and once the H and the ST16 connected motor auto start because of the slider and was unable to stop the motor needs to pull out the battery this even repeating install the firmware also unable to solve the problems, finally I decided to factory reset the ST16 and rebind the H and the ST16 the problem solved
